How to Record Binaural Audio
- Obtain a pair of external microphones.
- Space your microphones 7” (18cm) apart from each other.
- Place a dense object in the space between mics.
- Start recording.
How does binaural recording work?
Binaural audio is designed to work with headphones. Put on a pair, and click the sound locations above to hear a match being lit around you. Mono uses a single microphone to pick up sound, while stereo uses two, spaced apart from each other.
How to create a binaural mix?
The binaural recording technique builds on the principle of placing microphones on a human’s head – or an artificial head. The microphones’ position is either just outside each ear canal or at the bottom of the ear canal close to the eardrum.
What is binaural microphone?
A binaural microphone is a special stereo microphone that contains two prosthetic, human-shaped ears with microphone capsules embedded inside each ear canal. Binaural microphones capture audio the same way your real ears hear sounds.
How do I record spatial audio?
You can capture spatial audio using simple in-ear mics. Little can be changed in post-production but you can create good effects using free software plug-ins which can be used with most digital audio workstations and will allow steering of mono sounds around the listener.
Which is the best recording technique for binaural sound?
Thus binaural recordings sound the best if recorded using your personal HRTF. However, in general, everybody experiences a much higher envelopment of the surrounding sound, even though the HRTF is not their own. This is why the binaural recording technique is worth considering for many purposes.
Why is HRTF similar for left and right ears?
For a sound source directly ahead, HRTF is roughly similar for both the left and right ear because of the symmetry of our body. You can see peaks and notches on the plot which are caused by various wave effects, such as reflection of the pinna, diffraction on the head, etc… The same person as above, but this time sound source is to the left.
What can you do with a binaural headset?
Using the a binaural headset is very close to the HRTF measured with a blocked ear canal (to the right). This play was developed by students of the Danish National School of Performing Arts. Nanna-Karina Schleimann created sound design and musical compositions. In the play, the audience moves around among the actors.
How is binaural recording used in pose paranoia?
“Pose Paranoia”: Composition/sound effects for a scene. The binaural technique is designed for playback with headphones. If the binaurally recorded sound is played back by loudspeakers, some correction is needed. The correction is basically an inversed HRTF. As the HRTF changes with direction, it is complicated to design this inverted function.
